World: U.S. envoy to Kenya steps down

President Barack Obama's ambassador to Kenya announced his resignation on Friday ahead of the publication of a U.S. government audit that will be critical of his leadership of the most important embassy in East Africa.

A former two-star Air Force general, Ambassador Scott Gration appears to have been forced to step down by how critical the audit will be. Gration said he was resigning because of differences in priorities between him and Washington.

Three U.S. Embassy employees told The Associated Press that Gration led the embassy using a "my way or the highway" military leadership style that didn't translate well in the civilian embassy world.

Drug possession for personal use OK'd by court

The Constitutional Court has ruled that people cannot be jailed for possessing cocaine and marijuana for personal use.

The decision ratifies a previous Supreme Court ruling that said people cannot be jailed for possession of a so-called personal dose. A 2009 law placed the dose at up to 20 grams of marijuana and one gram of cocaine.

While striking down that provision, the court did not mention a quantity acceptable for personal use. Chief prosecutor Eduardo Montealegre said Friday that the decision does not amount to drug legalization.

Man stabbed to death near Olympic Park

U.K. police say a man has died from stab wounds after a fight at the shopping mall that will be the gateway to London's Olympic Park.

Authorities said the man was killed Friday afternoon on the ground floor of the Westfield shopping mall and another has been arrested.

The new mall links the Stratford train, bus and subway stations to the Olympic Park in east London. Spectators will have to walk through it to reach a number of Olympic venues for the games.

Stratford has traditionally been a poor neighborhood with a relatively high crime rate but the Summer Olympics has helped regenerate the area. Police gave no further details about the man's identity or what caused the fight.
